Inspite of being a Shatabdi
This is slower than 12623 MAS TVC mail by 13mts
MAS TVC super AC by 28mts
22639 MAS ALLP SF takes 7hrs and 8 minutes to CBE which is just 3 mts more
12697...
more... MAS TVC SF takes 7hrs and 9 minutes to Podanur which is just 4 mts more
They can justify saying it is due to slack as Shatabdi terminates at CBE. Still this only shows this Shatabdi is marginally faster than Super fast trains in this section, yet commands a premium fare.
The speed difference between SF and Shatabdi is higher much higher in Delhi Kanpur, Mumbai Ahmedabad, Delhi Amritsar, Chandigarh sections.
But in SR there is hardly any speed difference
